Updating dataset in vb net
Using Sql Dependency to monitor SQL database changes There is also similar conversation going on just a few below yours I already read all this and that. Update(QADStatus, "Inventory_Test") Msg Box("SQL Server DB was updated " & Chr(13) & "Check Server Explorer to see changes") End Sub Q:... A: Read this tutorial Entire section of tutorials Parameterizing Your SQL Queries: The RIGHT Way To Query A Database. Data Relation Public Class Form1 Public QAD As Sql Data Adapter Public Inventory_Test As Sql Data Adapter Public QADStatus As Data Set Private Sub Form1_Load(By Val sender As System. Open() Dim sql String As String sql String = "" sql String = "SELECT PT_Part, PT_STATUS, PT_DRWG_SIZE FROM PT_MSTR" QAD = New Sql Data Adapter(sql String, obj Conn) QADStatus = New Data Set QAD. To insert, update, and delete data using a Data Adapter, you create an Ole Db Command object with INSERT, UPDATE, and DELETE statements and set the Insert Command, Update Command, and Delete Command properties of the data adapter to Ole Db Command.You can avoid building Command objects manually by using Command Builder. This object reads the database and creates an in-memory copy of that part of the database that your program needs. In addition to being reliable and easy to use, Data Set supports both a hierarchical view of the data as XML and a relational view that you can manage after your program disconnects. As you can see from listing 5-48, I created a filled Data Set and created a new Data Row using the Data Table. After creating a Data Row, I set its column values and called the Data Adapter's Update method and displayed data in the Data Grid.I added new rows to the Customers table with Customer Id, Customer Name, and Company Name (named Tst ID, Lana Jackob, and Mindcracker Inc., respectively). Adding data using a Data Adapter's Update method Listing 5-49 shows an example that edits row data.
Data Relation Public Class Form1 Private QAD As Sql Data Adapter Private Inventory_Test As Sql Data Adapter Private QADStatus As Data Set Private Sub Form1_Load(By Val sender As System. Open() Dim sql String As String sql String = "" sql String = "SELECT PT_Part, PT_STATUS, PT_DRWG_SIZE FROM PT_MSTR" QAD = New Sql Data Adapter(sql String, obj Conn) connection String = "" connection String = "My Connection to Inventory_Test Database" obj Conn = New Sql Connection(connection String) obj Conn. I just need to know how to take the data from the Data Set(QADStatus) into Database2(PT_MSTR_TEMP).
The Find method returns the row with Customer Id = Tst ID.
After that I assign values of the row and call the Data Adapter's Update method. Updating data using the Data Adapter's Update method Deleting a row is simple.
Load Dim connection String As String connection String = "My connection to QAD Database" Dim obj Conn As New Sql Connection(connection String) obj Conn. Columns("Inventory_Number") data_relation = New Data Relation("QADto Inventory_Test", QADtable, Inven Table) QADStatus. I know to first research before posting a question...
Data Source = QADStatus End Sub Private Sub Button1_Click(sender As System. Would you like a screen shot on my HISTORY/Cookies...
